Can children born before their parents married still be with parents names when they were registered. Donald Daniel D Bullivant and wife have 5 children, 4 have name Bullivant on birth certificate and mothers name McNally. Mother had married several years before to an American GI and then got divorced. 2 of the children were definitely born before marriage but still have both parents names in the Free BMD. A fifth one seems to have a different Mothers name but there is no details of a marriage between Donald and the mother so could illegitimate children still be registered with fathers name?
